protected double computePrefHeight(double width, double topInset, double rightInset, double bottomInset, double leftInset)

Overrides javafx.scene.control.SkinBase.computePrefHeight.

Doc from javafx.scene.control.SkinBase.computePrefHeight.

Calculates the preferred height of this SkinBase. The default implementation calculates this height as the height of the area occupied by its managed children when they are positioned at their current positions at their preferred heights.

protected double computePrefWidth(double height, double topInset, double rightInset, double bottomInset, double leftInset)

public void dispose()

Overrides javafx.scene.control.SkinBase.dispose.

Implements javafx.scene.control.Skin.dispose.

Doc from javafx.scene.control.SkinBase.dispose.

Called when a previously installed skin is about to be removed from its associated control. This allows the skin to do clean up, like removing listeners and bindings, and undo any changes to the control's properties. After this method completes, getSkinnable() and getNode() should return null.

Calling dispose() more than once has no effect.
